LU BRICATO R.

SPECIFICATION forming part of Letters Patent No. 439,795, dated November4, 1890.

Application filed July 24:, 1890- Serial No. 359,785. (No model.)

To all whom, it may concern.-

Be it known that I, WILLIAM J. Timon, of Dunkirk, in the county ofChautauqua and State of NeWYork, have invented certain new andusefulImprovements on a Lubricator and I do hereby declare that the followingdescription of my said invention, taken in connection with theaccompanying sheet of drawings, forms a full, clear, and exactspecification, which will enable others skilled in the art to which itappertains to make and use the same.

This invention has general reference to improvements in lubricators; andit consists, essentially, in the novel and peculiar combination of partsand details of construction, as hereinafter first fully set forth anddescribed, and then pointed out in the claims.

In the drawings hereinbefore referred to, Figure 1 is an elevation of myimproved lubricator. Fig. 2 is a longitudinal sectional elevation. Fig.3 is a plan of the same.

Like parts are designated by corresponding letters of reference in allthe figures.

The object of this invention is the production of a simple lubricatingoil-cup for shaftbearings and the like, which can be regulated to feed acertain quantity of lubricant in a predetermined space of time, andwhich can be entirely stopped by simplyturning a lever. To attain thisresult, I construct my lubricator substantially as shownin the drawings,and in which A designates the bottom piece of my lubricator, it beingprovided centrally with an upwardly-projecting tube F, the upper end ofWhich passes through an aperture in the top piece B, as shown in Fig. 2.Between these top and bottom pieces is interposed a glass cylinder C,thereby producing a tight chamberD for the reception of the lubricant,Washers d d being placed between the edges of the cylinder and the topand bottom pieces to make a tight joint.

The tube F, before mentioned, is provided with a passage 0, leading intoits interior from the chamber D, for the escape of the lubricant, and ithas at its upper end an external screw-thread, over which fits a cap H.

The top piece B has in its upper surface and surrounding the tube F anannular boss P, over which fits a plate G, as clearly shown thereception of the points i of the lever I, as.

clearly illustrated in Fig. 1.

\Vithin the bore of the lever I, as well as the cap 11 and theprojection 72, there is located a tubular sleeve K, fitting therein witha'sliding fit, and which is provided at its lower extremity with aflange is, said sleeve being soldered or otherwise secured to the leverI at its upper end. The inner bore of the sleeve K is internallyscrew-threaded for the reception of the externally-screw-threadedportion at of a spindle N.

In the interior of the tube F, between the flange 7t and the cap H,there is located a spiral spring R to force the said sleeve downward.

The bottomipiece A is provided centrally with a downwardly-pointing boss0, havinga nozzle P. In the interior of this boss and nozzle there is apassage 0, communicating with the interior of the tube F, a valve-seat abeing located in said passage, so thatit may be closed by a.needle-point a on the lower end of the spindle N, as shown in Fig. 2.

Over the screw-threaded boss 0 on the bottom piece A fits a cup-shapedbody E, provided with openings e,which are preferably fitted with glassdisks, through whichthe passage of the lubricant from the nozzle P maybe seen. This cup has at its lower end the usual shank 6, provided witha wrench-section e for screwing the lubricator into position.

The lever I is provided with a handle I, wherewith it may be revolved,and the spindle N has at its upper extremity a button N (having apointer M, as hereinafter described) for regulating the feed of thelubricant. Upon the screw-threaded portion at of the spindle N islocated a disk J of proportionately large diameter, and having upon itsupper face a series of radial divisions J, representing predeterminedamounts of lubricant that will escape from the lubricator in a fixedspace of time, so that the operator may regulate the amount of theoutflowing liquid in a manner hereinafter to be referred to.

To fill the chamber D, there is an aperture 1) in the top piece B, andwhich is closed by the plate G, before mentioned.

In the present'instance the divisions on the face of the disk representdrops of liquiddischarged per minute, although other suitable graduationmay be used, and the pointer M is so arranged on the spindle N withrespect to the dial that when the said spindle is upon the valve-seat a,and the cam I seated, or in the position shown in Fig. 2, the saidpointer Mwill indicate the largest quantity of lubricant that can passout of the chamber D within said time, when the lever I is partlyrevolved and seated in the notches in the crowns of the projections h,as shown in Fig. 1. Should it be desired to lessen the quantity oflubricant passing from the lubricator, the lever is again seated in thebottom of the notches, and then the valve-spindle turned by the buttonuntil the desired quantity is indicated by the pointer, when the lever Iis again raised and the luli icator resumes its function.

It is evidentthat when the leveris completely depressed and the spindlerevolved the sleeve K will rise and with it the lever I, thereby givingthe lever I less lift when afterward revolved, for obvious reasons. Itis also evident that the disk J serves the double purpose of anindicator-dial and a lock-nut to prevent the spindle N from being freelyrevolved, it being borne in mind that the disk J when turned in theproper direction binds the spindle N to the tube in the manner of alock-nut, while slightly loosening it enables the spindle to be revolvedby the button N. This disk,however, when screwed down upon the tube willalways return to the same spot relative to the tube, and will thereforenot affect the proper indications of the pointerM.

One of the advantages of my device over others is that I can easilygrind the valve stem and seat to a tight fit in case of leakage bysimply revolving the spindle until the sleeve and lever have beenscrewed up high enough to clear the projections 71, when by turning thehandle I the spindle may be revolved to grind or wear the spindle to theseat, the spiral spring R in this case assisting in pushing the valve toits seat.

This device can be produced at a very low cost, it being composed ofcomparatively few parts, requiring but little time and labor tomanufacture. It is preferably produced in brass, so that it may bereadily polished and plated, and when so finished will present a veryneat and attractive appearance,

Having thus fully described my invention, I claim as new and desire tosecure to me by Letters Patent of the United States- 1. The improvedlubricatorhereinbefore described, consisting, essentially, of the topand bottom pieces and the interposed glass cylinder, the tube centrallyupon the bottom piece passing through the top piece and screwthreaded atits upper end and provided with an aperture and avalve-seat at thebottom of the tube, the cap screwed tothe upper end of said tube andbearing against the top piece and provided with cam-shaped projectionsat its upper end,the cam-shaped lever engaging said cams, the internallyscrew threaded sleeve within said tube having the flange at its lowerend, the spiral spring interposed between the fiange and cap, and thescrewthreaded valve-spindle having the button and lock-nut, as and forthe purpose set forth.

2. In lubricators, the combination, with the oil-reservoir, of the cap Hon the upper end thereof, the cam-shaped projections on the upper end ofsaid cap, the cam-lever engaging the sam e, the interiorly-screw-threaded sleeve, the valve-spindle provided with thepointer on its upper end, and the combined lock-nut and disk having thegraduations in its face, substantially as and for the object stated.

In testimony that I claim the foregoing as my invention I have heretoset my hand in the presence of two subscribing witnesses.

WILL. J. 'IYNON.
